Space/Terrestrial Mobile Networks


Book Description

Space/Terrestrial Mobile Networks Internet Access and QoS Support covers the design of a Global Mobile Broadband System (GMBS) based on the results of the European Commission's Framework Programme 5 Information Society Technologies (IST) Project SUITED. Many of the latest concept in mobility solutions, network design techniques and internet technologies are presented. The SUITED project has addressed a number of technical issues that are very much state-of-the-art. The presentation of such material in the form of a design of a real network provides a unique source of information. This book: Addresses the important topic of heterogeneous networks and the underlying tecyhnologies Describes how to design an integrated satellite/terrestrial infrastructure where all the network components are fully merged together and integrated with the Internet Core network Presents the service scenarios and system requirements of the Global Mobile Broadband System (GMBS) Discusses the necessary QoS support and defines the novel admission control scheme Gauge & Gate Reservation with Independent Probing (GRIP) Covers mobility management including Mobile-IP support and a QoS Support Module (QASM) Describes the functional and network architectures and presents signalling protocols for mobility management in GMBS Presents the design of signalling protocols and their implementation using the Specification and Description Language (SDL) Space/Terrestrial Mobile Networks Internet Access and QoS Support has an accessible and practical approach to the subject and addresses in detail, the important topic of heterogeneous networks and the underlying technologies that make this concept possible.







Undersea Fiber Communication Systems


Book Description

DescriptionThis book provides a detailed overview of the evolution of undersea communications systems, with emphasis on the most recent breakthroughs of optical submarine cable technologies based upon Wavelength Division Multiplexing, optical amplification, new-generation optical fibers, and high-speed digital electronics. The role played by submarine-communication systems in the development of high-speed networks and associated market demands for multiplying Internet and broadband services is also covered.Importance of This TopicThis book will fill the gap between highly specialized papers from large international conferences and broad-audience technology review updates. The book provides a full overview of the evolution in the field and conveys the dimension of the large undersea projects. In addition, the book uncovers the myths surrounding marine operations and installations in that domain, which have remained known so far to only very few specialists.

Global Mobile Satellite Systems


Book Description

Global Mobile Satellite Systems - A Systems Overview makes mobile satellite communications understandable for communication engineers, candidates for an engineering degree, technicians, managers, and other decision makers such as financiers and regulators. It provides a systems oriented top-level view of mobile satellite communications. In particular, it focuses on Global Mobile Satellite Systems (GMSS) including active programs such as Globalstar, IRIDIUM, ORBCOMM, ACeS, and Thuraya, or so-called the second generation mobile satellite systems class. The authors start with a brief description of three generations of satellite systems in use or planned in the telecommunications industry. Selected systems architectural trades are identified and explained to illustrate how various GMSS systems are formulated, developed and evaluated. It includes an examination of market demand trends, business trades, regulatory issues as well as technical considerations. Major issues are examined in trade study style to provide easy access to key information. Key systems drivers such as orbit trades between LEO's, MEO's, and GEO's, frequency, protocols, customer bases, and regulatory and engineering issues are included. This book should appeal to individuals interested in the basic elements of Global Mobile Satellite Systems.

Moving Broadband Mobile Communications Forward


Book Description

The deployment of 4G/LTE (Long-Term Evolution) mobile networks has solved the major challenge of high capacities to build a real broadband mobile internet. This was possible mainly through a very strong physical layer and flexible network architecture. However, bandwidth-hungry services such as virtual reality (VR) and augmented reality (AR), have been developed in an unprecedented way. Furthermore, mobile networks are facing other new services with extreme demand for greater reliability and almost zero-latency performance, like vehicle communications and the Internet of Vehicles (IoV). Therefore, industries and researchers are investigating new physical layers and softwarization techniques and including more intelligence in 5G and beyond 5G (B5G/6G). This book discusses some of these softwarization techniques, such as fog computing, cloud computing, and artificial intelligence (AI) and machine learning (ML). It also presents use cases showing practical aspects from 5G deployment scenarios, where other communications technologies will co-habit to build the landscape of next-generation mobile networks (NGMNs).




GSM


Book Description

The Global System for Mobile Communication (GSM) is undoubtedly the most successful second generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM systems and its derivatives DCS-1800 and PCS-1900. The objective of the book is to address new concepts in the GSM system, dealing with both standardised features as well as theoretically and technologically feasible improvements, which contribute to evolutionary changes in general. Dynamic evolution of GSM presents a platform for the Universal Mobile Telecommunication System (UMTS) introduction and major trends in UMTS development will be addressed in this book, in particular progress towards new radio interface. The book is the collection of individual contributions from a number of authors. The intention of the editors was to gather the most prominent specialist in the GSM area. Ongoing efforts in GSM standardisation are focused on Phase 2+ with items planned to be added gradually on demand. Being mostly independent of each other, each of them could be introduced with little impact on the rest of the system. Speech remains the prime service of cellular systems with ongoing work on spectral efficiency taking into account the trade-off between cost of the system and transmission quality. Most notable result from novel speech service implementations is the introduction of new Enhanced Full Rate (EFR) speech coder. International railway organisation (Union Internationale des Chemins de Fer - UIC) has influenced the development of Advanced Speech Call Items (ASCI).
